Abstract: A software interface used in designing communications circuits receives input from a user (20). In response, the software interface initiates accessing of a route plan (16) comprising a first route point group (38) associated with a first circuit end point (34), a second route point group (38) associated with a second circuit end point (34), and one or more routes (32) connecting the first and second route point groups (38). Each route (32) is available for use in designing the circuit. The software interface also initiates selection of a route (32) according to the route plan (16) and initiates the automatic assignment of the selected route (32) to the circuit in designing the circuit. The software interface provides information to the user (20) reflecting assignment of the route (32) to the circuit. The route plan (16) may be selected from among multiple route plans (16) according to a service application (14) automatically derived from an associated circuit order.

Abstract: A computer-implemented system (10) for designing communications circuits includes one or more route plans (16) each with a first route point group (38) for a first circuit end point (34), a second route point group (38) associated with a second circuit end point (34), and one or more routes (32) connecting the first and second route point groups (38). Each route (32) is available for use in designing the circuit. A design engine (12) accesses a particular route plan (16), selects a route (32) according to the route plan (16), and automatically assigns the selected route (32) to the circuit in designing the circuit. The design engine (12) may select the particular route plan (16) from among multiple route plans (16) according to a service application (14) that is automatically derived from an associated circuit order.

Abstract: An intermediate scrambling device for a radiotelephone system is disclosed by which it is possible to establish and maintain scrambled communications between an originating scrambler terminal and the most distant companion scrambler on the circuit. The intermediate scrambler may establish and maintain the scrambled communications if it is the most distant scrambler, or it may become transparent to a more distant scrambler.
